For the uninitiated (like me) who arrive here via Google, the commands were:
# ha-manager remove vm:100
# ha-manager add vm:100 -group cluster1group
Remove 'vm:100' and 'cluster1group1' with values for your environment, of course. That can also be done via the WebUI.
How do I recover from a failed migration?
-= Current status =-
# qm migrate 100 node2 --online
(from daemon.log)
Mar 22 17:07:00 stout pve-ha-crm[2187]: ignore crm command - service already on target node: migrate vm:100 node2
The VM is still running fine. `ps` confirms kvm is running on...
